5.8 GHz CMOS全集成低噪声放大器设计
Design of a 5.8 GHz and Fully Integrated CMOS Low Noise Amplifier
摘要
Abstract
In view of the problem of needing synchronous matching of noise and input impedance in the LNA design in any given power,in this paper,a 5.8 Ghz CMOS low noise amplifier which supports the IEEE 802.11a WLAN standards is presented utilizing a standard TSMC 0.18 μm RF process by using the cascade structure and power-constrained simultaneous noise and input matching technique (PCSNIM).The noise figure (NF) of the proposed LNA at the central frequency is only 0.972 dB.The simulation results demonstrate that the LNA has a power consumption of 6.4 mW,a gain of 17.04 dB,and an input 1 dB compression point (P1 dB) about-21.22 dBm while at 1.8 V supply voltage.The proposed LNA also achieves good input and output match performance.关键词
